Try the key for the lid and turn the lock, then the central locking should lock it.
If its not shutting properly you can adjust the upside down "U" shaped bits of metal on inside of tray with the nuts to raise or lower it to suit the lid latch (sorry cant seem to find words to explain).
I've got mine so that when I close lid, I have to lightly push down and I can hear a click when the lid latch catches, just to keep a tight seal.
